Precision Machining for Pneumatic Systems & Hydraulic Fittings Manufacturers

When pneumatic systems fail, production lines stall. That’s why manufacturers of air-powered tools, factory automation equipment, and hydraulic fittings rely on Buell Automatics for components that hold up under pressure—literally. Since 1966, we’ve been precision machining and manufacturing the small but essential parts that keep compressed air systems running at their best.

Why Pneumatic & Hydraulic Fitting Manufacturers Need Better Components for Precision Machining and Manufacturing

Compressed air systems operate under unique stresses:

  • Repeated pressure cycling (0-150 PSI typically)
  • Metal-on-metal wear in valves and cylinders
  • Moisture that causes corrosion
  • Vibration from reciprocating motion

We precision machine and manufacture parts to address these challenges, whether for OEM pneumatic tool manufacturers or hydraulic fitting manufacturers requiring leak-proof connections.

Main Parts We Produce

Our Swiss screw machines and CNC lathes regularly produce:

For Pneumatic Systems:

  • Air valve bodies and spools
  • Cylinder rods and end caps
  • Fittings with NPT, BSPP, or ORB threads
  • Actuator shafts and bushings

For Hydraulic Fittings Manufacturers:

  • JIC flare fittings (37° and 45°)
  • ORB (O-ring boss) adapters
  • SAE straight thread ports
  • Compression fittings for high-pressure lines

Material Science Matters in Fluid Power

We select metals based on their real-world performance:

MaterialBest ForWhy it works
12L 14 SteelPneumatic FittingsMachines cleanly, good strength
303 StainlessHydraulic AdaptersCorrosion resistance, durable threads
6061 AluminumValve BodiesLightweight, good thermal properties
Brass C36000Air Line ConnectorsMachinable, corrosion resistant

Hydraulic fitting manufacturers know that even microscopic imperfections can cause leaks. Our processes prevent this:

  • Controlled Thread Cutting – Using ground thread tools for perfect form
  • Surface Finishing – Achieving Ra <32 µin on sealing surfaces
  • Dimensional Checks – Verifying every critical diameter stays within ±0.0005″

Industry Needs

We regularly machine parts compliant with:

  • SAE J514 (hydraulic tube fittings)
  • ISO 1179 (compressed air connections)
  • ANSI B1.20.1 (pipe thread standards)

Our ISO 9001:2015 QMS system documents every step—from material certification to final inspection—so hydraulic fittings manufacturers can trust the components they receive.

A Partner for Prototyping & Production

Whether you’re developing a new pneumatic tool, redesigning a hydraulic manifold or needing replacement parts for legacy equipment we can help with:

  • Small test batches (as few as 25 pieces)
  • Production runs (50,000+ units annually)
  • Reverse engineering discontinued parts
